Abstract
L'invention concerne un procédé de déshydratation d'une suspension aqueuse de matières solides, consistant à: ajouter à la suspension un adjuvant de floculation, ce qui permet à la suspension de floculer en vue de sa déshydratation. Ledit adjuvant de floculation est une composition aqueuse renfermant un premier et un second floculants polymères ioniques solubles dans l'eau, la quantité de premier floculant étant en excès par rapport à celle du second, le premier et le second floculants formant des particules de précipité d'ions antagonistes, et la quasi-totalité de la partie du premier floculant qui n'est pas contenue dans les particules de précipité d'ions antagonistes se trouvant en solution. L'invention est caractérisée en ce que les conduits de transfert et de dosage sont fabriqués de telle sorte que sensiblement aucune des particules du précipité d'ions antagonistes n'est brisée ou dispersée après sa formation et avant son ajout dans la suspension.
